Ti-bearing analog of eudialyte. Alluaivite from Khibiny didn't show fluorescence in UV-lights. Chemical composition of the mineral is very similar in Khibiny and in Lovozero, but alluaivite in Khibiny, differing from the Lovozero one, bears smaller amounts of Mn, Nb, K, Sr and Cl, and the greater quantities of Ca and Ti; it contain Fe and S also.
